Yup here see a huge difference in my serially connected 200Mhz CPU very simple display touchscreens relating to much pixelation and "slowness" of stream. What is nice though is that I touch the smaller CCTV video and it enlarges to the size of the screen which provides a better view.

With another similiar IP connected touchscreen; the streaming is very good. The embedded controller actally just provides the links (it has no display) to the connected touchscreen which works really well.

My mobile configurations utilize tiny pixel sized multiple window video motion screens which work well as the pixel sizes are very small.
